iot-sensortag: Allow reconnect after a failed connection attempt

A disconnected sensor tag can be tried to be reconnected by clicking
on the chart area or starting rescan from the Sensor settings menu.
During a (re)connection process a progress indicator is shown to
the user.

The user has a possibility to disconnect (and reconnect) a
currently connect SensorDataProvider

A new state, 'NotFound' is added in SensorTagDataProvider to
distinguish between states when a Sensor Tag has not been discovered
at all, and when it has already been discovered but is has been
disconnected.
